Ideas;

cd to directory
tree -afi | sed '/directory,/d' | sort -d | cut -c 3- >list
#sed '/directory,/d' could be sed '/directories,/d' depending

while read line
 do
locate $line
done <list

There are a few problems though,

It's not super fast (maybe make a seperate db?)
if filenames have numbers in them (seems maybe your files are uppercase only?)
locate tends to find EVERYTHING even close to $line, so grep what paths ya
want.
not sure on links?
maybe find instead?

good luck, please let me know what ya use, thanks

bests,
eddie
